Battery storage for Wind Power energy

The new concept will be piloted in the world’s first floating wind farm, the Hywind pilot park off the coast of Peterhead in Aberdeenshire, Scotland.

Batwind will be developed in co-operation with Scottish universities and suppliers, under a new Memorandum of Understanding (MoU) signed in Edinburgh on 18 March between Statoil, the Scottish Government, the Offshore Renewable Energy (ORE) Catapult and Scottish Enterprise.

Battery storage has the potential to mitigate intermittency and optimise output. This can improve efficiency and lower costs for offshore wind. The pilot in Scotland will provide a technological and commercial foundation for the implementation of Batwind in full-scale offshore wind farms, opening new commercial opportunities in a growing market.

“Statoil has a strong position in offshore wind. By developing innovative battery storage solutions, we can improve the value of wind energy for both Statoil and customers. With Batwind, we can optimise the energy system from wind park to grid. Battery storage represents a new application in our offshore wind portfolio, contributing to realising our ambition of profitable growth in this area.”

Statoil will install a 1MWh Lithium battery based storage pilot system in late 2018. This equals the battery capacity of more than 2 million iPhones.

The pilot will be part of Hywind Scotland, an innovative offshore wind park with five floating wind turbines located 25 km offshore Peterhead. The wind park is currently under construction and start of electricity production is expected in late 2017.

A structured programme is now being established under the MoU to support and fund innovation in the battery storage area between Statoil and Scottish industry and academia. This programme will be managed by ORE Catapult and Scottish Enterprise.

“We’ve worked with Statoil for a number of years to deliver the Hywind project, so it’s fantastic to remain involved in this next stage of battery storage innovation. This is exactly the kind of innovation in the energy sector we’re keen to encourage and support as it may have potential to advance industry growth in Scotland.”
